The specific embodiment
The core of the utility model is for providing a kind of gas-liquid separator; The structural design of this gas-liquid separator can guarantee needed freezing oil mass in the compressor operating process on the one hand, can also avoid too much refrigeration oil to get into compressor on the other hand it is caused liquid hammer.In addition, another core of the utility model is that a kind of refrigeration system that comprises this gas-liquid separator is provided.
In order to make those skilled in the art understand the technical scheme of the utility model better, the utility model is done further to specify below in conjunction with accompanying drawing and specific embodiment.
Please refer to Fig. 2, Fig. 2 is the structural representation of gas-liquid separator among a kind of embodiment of the utility model.
In one embodiment, the gas-liquid separator that the utility model provided is used for refrigeration system, comprises cylindrical shell 1, and cylindrical shell 1 is connected with inlet tube 2 and outlet 3, and outlet 3 comprises the mouthpiece portion 31 that stretches in the cylindrical shell 1 and is in the tube body portion 32 of cylindrical shell 1 outside; Mouthpiece portion 31 extend into the upper chamber of cylindrical shell 1 with its mouth of pipe, and is provided with spill port 31a in the lower cavity positional interface pipe portion 31 of cylindrical shell 1; In addition, as shown in Figure 2, the both sides of cylindrical shell 1 are provided with the end socket 6 of sealing usefulness, also are provided with the installing plate 5 that usefulness is installed on the periphery wall of this cylindrical shell 1.
On the said structure basis, be connected with equalizing line between the upper chamber of the cylindrical shell 1 of the gas-liquid separator that the utility model provided and the tube body portion 32, so that the refrigerant pressure in the tube body portion 32 is slightly less than the refrigerant pressure in the upper chamber of cylindrical shell 1.
During work; Gas-liquid mixed attitude cold-producing medium gets into cylindrical shell 1 inner chamber from inlet tube 2; Wherein liquid is fallen in the lower cavity of cylindrical shell 1 from top to bottom, floats on the gas in the upper chamber of cylindrical shell 1, under the effect of external force; Gas gets into the mouthpiece portion 31 of outlet 3 and is derived by tube body portion 32, finally gets in the compressor; In this process, the refrigeration oil that is on cylindrical shell 1 bottom gets in the outlet 3 through spill port 31a, finally gets into compressor to lubricated.
In said process, because the refrigerant pressure in the tube body portion 32 is less than the refrigerant pressure in the upper chamber of cylindrical shell 1, thereby can be so that necessary freezing oil mass gets in the outlet 3 through spill port 31a, and then it is lubricated to it to get into compressor; Simultaneously, again because the refrigerant pressure in the tube body portion 32 only is the refrigerant pressure that is slightly less than in the upper chamber of cylindrical shell 1, thereby can avoids too much refrigeration oil to get in the compressor again and cause liquid hammer, thereby can guarantee the compressor operate as normal.
Need to prove that because the balanced action of equalizing line, when the compressor of system had just started, the ratio of the pressure of the upper chamber of pressure in the tube body portion 32 and cylindrical shell 1 was about 0.9; When system normally moved, the ratio of the pressure of the upper chamber of pressure in the tube body portion 32 and cylindrical shell 1 was about 0.95; On this basis; Can make explanations to the connotation that above-mentioned wording " is slightly less than ": that is the ratio of the pressure of the upper chamber of pressure in the tube body portion and cylindrical shell 1 is greater than 0.85; Less than 0.98, the numerical value in this scope all belongs to the implication category of " being slightly less than ".
On the basis of technique scheme, can make further design.Such as, as shown in Figure 2, equalizing line can be capillary 4.Capillary 4 is as equalizing line the time; Can make the upper chamber of cylindrical shell 1 be communicated with on the one hand with tube body portion 32; On the other hand because its circulation area is little, thereby can make refrigerant pressure in the tube body portion 32 more easily less than the refrigerant pressure in the upper chamber of cylindrical shell 1.In addition, the cost of capillary 4 is also lower.
In technique scheme, the structural design of another kind of equalizing line can also be provided.Such as, equalizing line comprises communicating pipe and choke valve, this choke valve is located at and is gone up its circulation area of control this communicating pipe, through the throttling action of this choke valve, can so that the refrigerant pressure in the tube body portion 32 less than the refrigerant pressure in the upper chamber of cylindrical shell 1.In addition, owing to the throttling of choke valve can be regulated, thereby can regulate the size of the difference of above-mentioned two refrigerant pressure, thereby can regulate the oil mass that gets into the refrigeration oil in the compressor according to actual needs.Such as, when compressor needed more refrigeration oil, choke valve can reduce the circulation area of communicating pipe, made the difference of two refrigerant pressure increase, and then increased the oil mass that gets into refrigeration oil in the compressor; Vice versa.
In addition, in above-mentioned any technical scheme, tube body portion 32 comprises the interface end 32a that is connected with the compressor of refrigeration system, and an end of equalizing line further is connected on the interface end 32a.Through balance near the refrigerant pressure of the interface end 32a of compressor and the refrigerant pressure of cylindrical shell 1 upper chamber; Thereby can control the oil mass of the refrigeration oil that gets into compressor more accurately and reliably; Thereby can more effectively guarantee needed freezing oil mass in the compressor operating process on the one hand, can also avoid too much refrigeration oil to get into compressor on the other hand it is caused liquid hammer.
In addition, the utility model also provides a kind of refrigeration system, comprises compressor; Refrigeration system also comprises the gas-liquid separator in above-mentioned any technical scheme, and tube body portion 32 is connected with compressor with its interface end 32a.Other parts of this refrigeration system can be with reference to prior art, and this paper no longer launches.
More than refrigeration system and gas-liquid separator thereof that the utility model provided have been carried out detailed introduction.Used concrete example among this paper the principle and the embodiment of the utility model are set forth, the explanation of above embodiment just is used to help to understand the method and the core concept thereof of the utility model.Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model principle, can also carry out some improvement and modification to the utility model, these improvement and modification also fall in the protection domain of the utility model claim.
